Shank-back sewing button sized 23mm (7/8"), 2 per card. The raised shank keeps stitches hidden and allows room for thicker fabrics so closures fasten smoothly without puckering. Well-suited to coats, jackets and knit garments, it provides a neat, low-profile finish that helps heavier fabrics drape cleanly. Use for replacements or to add a statement closure on outerwear, accessories and costume work.
